To all whcm it may concern: I I

Be it known that'I, CHARLES Wk LUT- TRELL, a citizen of the UnitedStates, residing at Bronte, in the county of Coke and State of Texas,have invented a new and useful Stalk Chopping or Cutting Roller; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in'theart to which it appertains to make and use the same. H v n v Thisinvention relates to a new and useful stalk chopper or cutter roller. 7

An object of the invention is to provide an improved device of thisnature, which is simple and eflicient in construction, and may bemanufactured very cheaply, 7

One of the features of the invention is to provide a revolving cutterofsuch a construction that the radial arms thereofwill yield incident tocoming in contact with the stalks, and in which the free ends of thearms are disposed at angles to which the cutting blades are attached,which blades are likewise angular in cross section.

A further object of the invention is to provide means such as sleeves,one at each end of the cylinder and designed to carry the radial arms,and which are so arranged on a tubular member of the cylinder, as to beadjusted annularly on the tubular member, whereby the cutting blades orknives may be twisted or disposed at an angle axially to the shaft ofthe roller, in order to permit the cutting blades or knives to have ashearing action on the stalks.

In practical fields the details of construction may be subjected toalterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, ashereinafter set forth, shown in the drawings and cla1med.

In the drawings :Figure 1 is a new 1n side elevation of the improvedcutting cylinder or roller constructed in accordance with the invention.Fig. 2 is an end elevation. Fig. 3 is a view in side elevation,illustrating the cutting blades or knives twisted or disposed at anangle. Fig. 4 is an end elevation showing the arms of the reel extendingexactly radially, and the angular ends of the arms eliminated.

therewith. This cutting roller or cylinder comprises a tube 2 consistingof two sleeved sections 3. a11d4 united or connected together as at 5,by meanscf the gear teeth or toothed connections. The outer ends of thesleeve sections are provided with arms 7, threaded in place as at Standhaving lock nuts 9. These arms taper toward the sleeve sections, asshown in order to make them thin enough, whereby the arms may yieldincident to the cutting knives or blades coming in contact with thestalks. The outer ends of the arm are. broader than the inner portionsthereof,,and are angularly disposed with the body ofthe arms, as shownat 10. These angularly disposed. end portionscarry the cutting. blades,or knives 11 which on cross section, are also angular, the part 12ofeach of said bladesis secured to the an:

. gular ends of two of the arms, that is, one at each end, while theportion 13 of the cutting blade or knife has a cutting edge 14. Boltsand nuts 15 and 16 are utilized for fastening the cutting blades orknives to the angular portions of said arms. A set screw or the like 16is utilized for fastening the sleeve section 3 to the shaft 1, whichforms a part of a stalk chopping machine. In order to dispose thecutting blades or knives angularly as shown in Fig. 3, the sleevesection 4 may be moved axially in the direction of the arrow (1, therebyspringing the arms con nected to the sleeve section 4 slightly, thesleeve section 4 may then receive a partial annular or rotary movementand allowed to spring back, so that the connections 5 will rengage. Inthis manner the cutting blades or knives may be arranged angularly asshown in Fig. 3, so that they may have a shearing action on the stalks.It will be observed that this angular arrangement may be increased ordecreased, so that the shearing action may be correspondingly increasedor decreased. Furthermore, it will be observed that only one set screwor the like 16 isnecessary to hold the sleeve sections in place. Inother words, the said screw holds one section in place, while theconnections 5 cause the other sleeve section to rotate with itsadjoining sleeve section. By the angular arrangement of the end portionsof the arms and the angular construction of the blades, said blades aredisposed in the proper position, when the cylinder or roller isrotating, in order to sever or cut the stalks. In Fig. 4 the arms arearranged radially, and the an.v

gular portion of the arms and the knives are dispensed with.

In practice the shaft of the cultivator (not shown) may be extended onone side of the machine, or on each side in order to accommodate threestalk cutters, in order to out three rows at once.

For the purpose of illustration there are only four knives shown,'but itis to be understood that six or more may be used.

The invention having been set forth, what is claimed as new and usefulis 1. In a cutting roller or cylinder, a shaft, a tubular member on theshaft comprising two sleeve sections having their adjacent ends providedwith gear tooth connections thereby uniting the sleeve sections axiallyon the shaft, means for securing one section to the shaft, the outerends of the sleeve sections having arms, and cutting blades or knivessecured to the outer ends of said arms.

2. In a cutting roller or cylinder, a shaft,

' a tubular member secured on the shaft to member comprising twosections having axially uniting means whereby one section may beadjusted annularly to dispose the cutting blades at different angles soas to produce a shearing action.

3. In a cutting roller or cylinder, a shaft, a tubular member secured onthe shaft to rotate therewith, arms projecting radially from theopposite ends of the tubular member, said arms being tapered toward thetubular member and being resilient and having angular ends, cuttingblades or knives angular in cross section, means for securing the bladesto the angular ends of the arms, said tubular member comprising twosections having axially uniting means whereby one section may beadjusted annularly to dispose the cutting blades at different angles soas to produce a shearing action.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. 7
